Lucy Brown, Ph.D., clinical professor in the Saul R. Korey Department of Neurology and of neuroscience at Albert Einstein College of Medicine of Yeshiva University, is the corresponding author of the study. This is the third publication in which Dr. Brown and her research group demonstrated that primitive reward and survival systems are activated in people who look at their beloved.
Using functional magnetic resonance imaging (fMRI), researchers recorded the brain activity of 15 college-age adults who had recently been rejected by their partners but reported that they were still intensely "in love." Upon viewing photographs of their former partners, several key areas of participants' brains were activated, including the ventral tegmental area, which controls motivation and reward and is known to be involved in feelings of romantic love; the nucleus accumbens and orbitofrontal/prefrontal cortex, which are associated with craving and addiction, specifically the dopaminergic reward system evident in cocaine addiction; and the insular cortex and the anterior cingulate, which are associated with physical pain and distress.
By tying these specific areas of the brain to romantic rejection, the research provides insight into the anguished feelings that can accompany a break-up, as well as the extreme behaviors that can occur as a result, such as stalking, homicide and suicide.
"Romantic love, under both happy and unhappy circumstances, may be a 'natural' addiction," said Dr. Brown. "Our findings suggest that the pain of romantic rejection may be a necessary part of life that nature built into our anatomy and physiology. A natural recovery, to pair up with someone else, is in our physiology, too."

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
